I am looking for an easy to use inventory management system for my new store, which I will be opening in three months. I will spend the next three months entering each item I sell into some type of database. What I need to know is:

What software would I need?Can I use a MAC? or do I need a PC?What hardware do I need? I want to be able to place a printed barcode on each item and also be able to scan in each sale I make and have the item removed from the inventory. I am quite intimidated by quickbooks POS because the reviews say it is definitely NOT for beginners. Is there something out there that is simpler? I don't need to do any invoicing. I just need to enter items to inventory, print bar codes on each item, and then scan them out of inventory when I make a sale. Any help would be greatly appreciated.
